Sln enhances LKB1-dependent apoptosis without affecting cell cycle progression or cell size. (A) Immunostaining against BrdU (top), phosphohistone H3 (middle), or Elav (bottom) in larval eye discs from the indicated genotypes. Arrowheads mark the second mitotic wave posterior to the morphogenetic furrow. Posterior at right. (B) Cytoplasmic GFP-marked flipped-out mitotic clones expressing LKB1 and Sln in larval fat body (top), wing disc (bottom left), or eye disc (bottom right). Filamentous actin was stained in fat body (top, red). Nuclear GFP is nonspecific autofluorescence in fat body (top). The time after clonal induction is indicated (bottom). (C and D) TUNEL (red) and AO (green) staining in larval eye discs from the indicated genotypes. The penetrances of apoptosis phenotypes were 100% (n = 10). Posterior at right. Bars, 50 μm.
